:) Tap the bottle nozzle to your table surface, to make sure all the glitter glue is down at that end, instead of the bottom of the bottle–if you need to, you can also “burp” it to make sure the air bubbles are out. Butt that nozzle tip at the edge of your top layer and hold it at a 45° angle and squeeze with even steady, pressure as you run it down the length of that layer and you should get a nice even bead! It won’t take too much practice and once you get the hang of it, you will be WHIPPING through those edges. And, for some reason, I find it oddly satisfying to glitter the edges of top layers that way, LOL!
